WINDOW-'SASH.

Specification of Letters Patent.

Patented April 10, 1906.

Application filed December 3, 1904. Serial No. 235,397.

To (Ml whom it may concern:

Be it known that I, OrHo M. OTTE, a citizen of the United States,residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented or discovered certain new and usefulImprovements in Wind ow-Sashes, of which'improvements the following is aspecification.

In the application filed of even date herewith I have described andclaimed certain improvements in sashes consisting of a frame withcross-bars and muntins and glazingstrips. This construction I have forthe convenience of description termed a threepiece sash.

The invention described herein relates to certain other and additionalimprovements in metal sashes for windows, such improvements consistingin formin the sash of two parts or members-i. 6., a frame with crossbarsand muntins and a glazing-strip formed integral with the said parts, anda removable glazing strip or strips.

The invention is hereinaftermore fully described and claimed.

In the accompanying drawings, forming a part of this specification,Fignre 1 is an elevation of my improved sash, the detachableglazing-strips being removed. Figs. 2 and 3 are section views or planesindicated, respectively, by the lines II II and III III, Fig. 1. Fig. 4is a detail view of one of the cross-bars, and Fig. 5 is a similar viewof one of the muntins.

In the practice of my invention. the frame may be U-shaped, as shown inthe application referred to, or continuous, as shown in Fig. 1, andconsists of a core 1 and a plate portion 4, preferably formed integralwith each other. Generally it is preferred to use the ordinarystructural T shape. The edges of the plate 4 of this section project 011both sides of the frame,for1ning flanges. The flanges rojecting inwardlyform glazing-strips, wl iile the outwardly-projecting flanges u on thesides of the frame form one wall of t. e groove for the reception of theguiding-plate 5, secured in the side wall of the window-opening. Themuntins or vertical members 3 are formed of similar T -sections, whichmay have their parts integral with each other or riveted together. Thecore 1 extends at the ends of the muntins, forming tongues 7, (shown inFig. 5,) which overlap the end pieces of the frame, rojecting intonotches cut in the core of the anus, as shown in Fig. 1. The core stripson one side of the several cores.

portions of the muntins are cut away at intermediate points to formnotches or recesses for the reception of the core on the cross-bar 2, asshown in Fig. 5. The cross-bars are formed of similar structural shapesand have the plate portion at the ends cut away to form tongues S, whichwill overlap and can be riveted to the side bars of the frame, the coresof the frame being cut away or recessed for the reception of thetongues. The plates of the cross-bars are also cut away at intermediatepoints to form notches for the reception 0" the plate portions of themuntins or vertical bars, as shown in Fig. 4. By this interlockingconstruction of the crossbars and muntins they will lie in the sameplane in the completed structure with the main frame or skeleton.

It will be observed that the inner plate portions of the frame and theplate portions of the muntins and cross-bars form glazipg e removableglazing-strips 6 are secured to the cores by screws or other suitablemeans, whereby they may be readily removed to re place broken glass. Theglazing-strips 6, secured to the core of the frame, project beyond thecore and along the sides of the frame and form, in connection with theprojecting portions of the plates of the frame, grooves for thereception of the guidingplates, which, as before stated, are secured toor embedded in the side walls of the windowopenings.

It will be observed that the sash is formed of two shapes or sections ofmetal-i. 6., a T shape, forming the frame, cross-bar, muntins, andglazing-strips for one side, and flat plates or strips, forming theremovable glazing strips.

I claim herein as my invention- 1. A window-sash having in combination aframe, muntins and cross-bars formed of T-shape'd bars, the flanges onone side of said bars, forming glazing-strips, and glazingstripsdetachably secured to the frame, crossbars and muntins, substantially asset forth.

2. In a Window-sash, the combination of a frame, muntins, cross -barsformed of T- shaped bars and interlocked at their points ofintersection, and glazing-strips detachably secured to the frame,cross-bars and muntins, substantially as set forth.

3. A window-sash having in combination, a frame, muntins and cross-b areformed of T- shaped bars, the flanges on one side of said muntins andextending beyond the core of the frame and forming with the outerflanges of the frame, guides for the frame, substantially as set forth.1

In testimony whereof I have hereunto set I 5 bars forming glazing-stripsand glazing-strips detachably secured to the frame, cross-bars andmuntins, the glazing-strips on the frame extending beyond the core ofthe latter and 5 forming with the outer flanges of the frame,

guides for the frame, substantially as set forth. my hand.
